New Guinea impatiens plant named ‘Kilogia’

ABSTRACT

A new and distinct cultivar of New Guinea Impatiens plant named ‘Kilogia’, characterized by its large bright red purple-colored flowers; upright and compact growth habit; and, dark green leaves with red-colored veins.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, and hereinafter referred to by the cultivar name ‘Kilogia’.

The new cultivar is a product of a planned breeding program conducted by the Inventor in Gensingen, Germany. The objective of the breeding program was to develop early-flowering varieties with numerous flowers, freely-branching and uniform plant habit, atttractive flower and foliage colors, and good flower form.

The new cultivar originated from a cross made by the Inventor of the proprietary selection identified as L72 as the male, or pollen parent, with the proprietary selection identified as L869 as the female, or seed parent.

The cultivar ‘Kilogia’ was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Gensingen, Germany, in April, 1997.

Asexual reproduction of the new cultivar by terminal cuttings taken at Gensingen, Germany, has shown that the unique features of this new cultivar are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kilogia’. These characteristics in combination distinguish ‘Kilogia’ as a new and distinct cultivar:

1. Large bright red purple-colored flowers.

2. Upright and compact growth habit.

3. Dark green leaves with red-colored veins.

Plants of the new cultivar can be compared to plants of the commercial cultivar ‘Apollon’, disclosed in U.S. Plant Pat. No. 8,429. However, in side-by-side comparisons conducted in Encinitas, Calif., plants of the new cultivar differ from plants of the cultivar ‘Apollon’ in the following characteristics:

1. Plants of the new cultivar are smaller, more compact, less vigorous and more uniform than plants of the cultivar ‘Apollon’.

2. Leaves of plants of the new cultivar are solid green whereas leaves of plants of the cultivar ‘Apollon’ may be variegated depending on light level.

3. Flowers of plants of the new cultivar are larger, more round and flatter than flowers of plants of the cultivar ‘Apollon’.

4. Plants of the new cultivar flower about 7 to 10 days earlier than plants of the cultivar ‘Apollon’.

A detailed comparison of plants of the cultivars ‘Kilogia’ and ‘Apollon’ appears in Chart A at the end of the specification.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph at the top of the sheet comprises a side perspective view of a typical plant of the cultivar ‘Kilogia’.

The photograph at the bottom of the sheet comprises a comparison close-up view of typical flower buds, flowers and upper and lower surfaces of leaves of the cultivars ‘Kilogia’ (left) and ‘Apollon’ (right). Flower and foliage colors in the photographs may differ from the actual colors due to light reflectance.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar ‘Kilogia’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The following observations, measurements and comparisons describe plants grown in 25-cm hanging baskets in Encinitas, Calif., under commercial practice in a polyethylene-covered greenhouse with day temperatures averaging 23° C., night temperatures averaging 19° C., and light levels about 3,000 foot-candles. Plants were about 17 weeks old after planting a rooted cutting.

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
